It’s crucial components responsible for supporting an aircraft during landing, takeoff and while on ground designed for stability
Landing Gear System
2
3 Primary Function of Landing Gear
Shock, Support and Stability
3
offer simplicity, lower maintenance costs, and better visibility during flight. However, they can be more challenging to handle on the ground due to limited forward visibility. 2 Wheel in front 1 Wheel in back
Conventional
4
It provides better ground visibility for pilots, improved handling during takeoff and landing, and greater stability on the ground. 1 Wheel in front 2 Wheel in Back
Tricycle Landing Gear
5
can be stowed inside the aircraft's fuselage during flight, reducing drag and improving aerodynamic efficiency. 1 Wheel in front 2 Wheel in back
Retractable Landing Gear
6
typically flat or slightly curved structures made of sturdy materials like metal, composite materials, or even reinforced plastics
Skids
7
allows an aircraft to operate both on land and on water. versatile and can be used for operations in various environments, such as flying to remote locations with limited landing options.
Amphibious Landing Gear
8
Design to absorb or dissipate the impact energy during landing Typically use springs, oleo strut(hydraulic shock)
Shock Absorbing Landing Gear
9
* Do not have the capacity to absorb or dissipate landing impact * Often found in smaller, lightweight aircraft or those designed for operation or very smooth surface
Non-Shock Absorbing Landing Gear
10
* Most common type of non shock absorbing landing gear * Utilize flexible spring steel, aluminum, or composite strut
Leaf-Type Spring Gear
11
* Shock load transfer to the airframe is direct with this * Curved spring steel landing struts
Rigid Landing Gear
12
utilizes bungee cord or rubber cords as form of shock absortion during landing process
Bungee Cord Landing Gear
13
Self contained hydraulic units that support an aircraft while on the ground and protect the structure during landing
Shock Struts
14
The landing gear provides the necessary support to hold the aircraft's weight during various phases of flight, especially during landings and ground operations
Support
15
Landing gear contributes to the stability of the aircraft during takeoff, landing, and taxiing
Stability
16
During the landing phase, the aircraft experiences a considerable amount of vertical force and impact as it touches down on the runway.
Shock Absorption
17
of an aircraft is a crucial component that plays a significant role in ground maneuverability. This system allows the pilot to control the direction of the aircraft during taxiing, takeoff, and landing on the ground.
Nose Wheel Steering System
18
is a type of steering mechanism in aircraft where the direction of the nose wheel is controlled by the pilot's input on the rudder pedals in the cockpit. This system is commonly
Pedal-Controlled System
19
is commonly used for nose wheel steering.
Tiller-Controlled System
20
Some aircraft feature a combination of tiller and pedal controls. This allows pilots to choose the method that best suits the specific taxiing situation. The tiller might be used for sharp turns or precise maneuvering, while pedals can be used for more general steering.
Combination System
21
While not a primary nose wheel steering system, (blank blank) plays a role in steering on the ground. By applying more brake pressure to one main landing gear wheel than the other, the aircraft can pivot, assisting in making turns, especially in situations where nose wheel steering alone may be insufficient.
Differential Braking
